[PATCH] docs: move s390 under arch

[Costa Shulyupin <costa.shul@redhat.com>]

and fix all in-tree references.

Architecture-specific documentation is being moved into Documentation/arch/
as a way of cleaning up the top-level documentation directory and making
the docs hierarchy more closely match the source hierarchy.
